Our Stories: Black Parents’ Experiences At K-12 Predominantly White Institutions, Jason Thompson

Dissertations

Black parents of Black children attending K–12 predominantly White institutions (PWIs) often experience stress as they navigate school environments where they may be perceived as uninterested, combative, or “token” members of the school community. These deficit-based perceptions can cause Black parents to limit school interactions, question whether their perspectives will be valued, and develop distrust toward school personnel. Although research has examined Black students’ experiences in PWIs, fewer qualitative studies have centered on Black parents’ stories. Capturing these experiences in parents’ own words helps challenge harmful stereotypes and offers schools, especially school counselors, deeper insight into strengthening relationships with Black …

Analyzing Label Structure And Regional Similarity In Watershed Data Via Spectral Clustering, Yifan Luo

25th Annual A. Paul and Carol C. Schaap Celebration of Undergraduate Research and Creative Activity (2026)

This project focuses on identifying patterns of seasonal transitions and nutrient salt fluctuations within the watershed environment. To capture the complex relationships between multiple sampling sites and environmental variables, we represent the watershed dataset as a weighted graph, where nodes correspond to water samples and edge weights reflect similarity in environmental conditions or nutrient concentrations. Using the Gaussian kernel function, we encode the connectivity structure of this network and quantify how similar different nodes are. We then perform spectral embedding by projecting the high-dimensional graph into a lower-dimensional space using the eigenvectors of the Laplacian matrix. This approach preserves the …

Palladium-Catalyzed Coupling Of Aryl Halides To Organometallics From Tertiary Alcohols, Joseph E. D'Amico, Annabelle G. Frederick, Nicholas S. Corey

25th Annual A. Paul and Carol C. Schaap Celebration of Undergraduate Research and Creative Activity (2026)

For years, the Suzuki-Miyaura reaction has served as an effective method of coupling various carbon-carbon structures, typically of aryl halides with aryl boronic acids. However, the Suzuki reaction is not without limitations, specifically with ortho-fluorinated aryl and heterocyclic boron compounds. The palladium catalyzed cross coupling reaction of tertiary alcohols with halides has shown potential in succeeding where the Suzuki reaction is limited. This research aims at exploring the extent of effectiveness in the use of tertiary alcohols in palladium catalyzed coupling reactions. Specifically, this work focuses on the change in reactivity depending on the aryl halide used.

The “How Many” Routine As A Catalyst For Computational Fluency And Student Participation, Lillian Iden, Ella Williams, Jen Munson, Sarah Larison, Leslie Yuqui

25th Annual A. Paul and Carol C. Schaap Celebration of Undergraduate Research and Creative Activity (2026)

It is not uncommon to hear adults claim they are bad at math or always disliked the subject. This negativity often stems from early mathematical experiences which ranged from boring to highly discouraging and embarrassing. Thus a new emphasis in mathematics education recommendations is to change the narrative and help students develop joy, wonder, and curiosity about mathematics (MAISA & GELN, 2023). This is reflected in defining computational fluency (skill in carrying out arithmetic procedures like addition or multiplication) as comprised of flexibility, accuracy, efficiency, and appropriate strategy use (NRC, 2001). The “How Many” Routine, in which a carefully-designed image …

Divergent Paths Towards Belonging: A Comparative Analysis Of Latina/O/E Domestic And International Student Experiences At A Pwi, Sebastian Lema, Rita Kagaju

25th Annual A. Paul and Carol C. Schaap Celebration of Undergraduate Research and Creative Activity (2026)

In this study, we examine how undergraduate international students from Latin America and domestic Latina/o/e students experience belonging and inclusion at a Predominantly White Institution (PWI). While existing research highlights systemic barriers and microaggressions faced by domestic Latina/o/e students, we address a critical gap by exploring the distinct challenges faced by international Latin American students. We ask how these groups’ experiences of inclusion, microaggressions, and support systems differ within a PWI context. Using qualitative interviews with 55 students (40 domestic, 15 international), we employed grounded theory to analyze themes such as classroom dynamics, feelings of inclusion/belonging, and institutional support.
